The best way to sand a deck is by cleaning it, sanding the boards and stairs with 60- or 80-grit sandpaper, and sanding the railings and posts with 80-grit sandpaper. You should sand in the direction of the wood grain to avoid damaging the timber. When sanding your deck, use medium pressure and aim for an even sand. Pressing too hard with a sander can damage decks, as most are softwoods.

Soda-blasting systems are slightly more expensive than sandblasting systems. To soda blast, you’ll need to spend a few hundred dollars for a blast hose and nozzle, a compressed air supply, a blast generator, a moisture decontamination system, and sodium bicarbonate media, a recurring cost because the powder is not reusable. To start with sandblasting, you will need to spend upwards of $30 for a blast pot, a blast gun, an air compressor, and sandblasting media, many of which are recyclable—further reducing the cost. The total cost for either will depend on the size of the system.

Seal joints, clean debris regularly, and address cracks promptly to maintain appearance and stability.

Costs depend on surface material, labor, debris disposal, and the type of blasting media used.
